Most of these are in Java or p5js formats
I started out using processing 2 then processing 3 came out and I used that for a while. What I really wanted was a good web version of processing processing.js was not too interesting for me. When p5.js cameout I used that a bunch on plunker.
Now I Primerly use p5.js and am getting back into processing 3 for some desktop uses.
